' OF NEWARK, NEW JERSEY, A CORPORATION OF NEW JERSEY BRACELET CHAINApplication filed June 14,

This invention relates to an improvement in the construction of aflexible bracelet or chain formed of a plurality of units hingedlyconnected together; and the object of this I invention is to provide asimple construction by which the units may be easily and quicklydetached one from another by manual manipulation of the parts forvarying the operating length of the bracelet.

A further object of the invention is to provide a bracelet having unitshingedly connected together, each unit being of such a shape that theconnection between the units may be readily accessible for attaching ordetaching purposes of the links.

The invention further consists in the overlapping of the end portions ofthe bracelet units with registering openings in these overlappingportions and the providing of resilient arms with outturned fingers orprojections which may be in U-shape if desired to enter the registeringopenings and hingedly connect the units together, the resilient arms ofthe U being accessible through the open side of a channel shaped linkconstruction for withdrawing the arms from the registering openings fordetachment of one link from another.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view of two link units of the bracelet chainconnected together.

Figure 2 is a sectional view from the underside thereof showing theU-shaped connector member for connecting the links together.

Figure 3 is a sectional view looking at the under side of the braceletwith one of the arms of the connector member withdrawn showing theresilient action thereof.

Figure 4 is a perspective view of the connector member.

In the bracelet market, there is a demand for a bracelet chain which hasits units easily attachable and detachable so that the working length ofthe bracelet or chain may be 1928; Serial naflaeasrs.

readily adjusted to fit the wrists of different wearers; and in order toaccomplish this result in a simple, practical and durable construction,I have formed the units with portions at theirends overlapping and haveprovided suitable openings in these overlapping portions to receive anoutwardly extending finger or projection on a resiliently mounted arm,which for convenience and simplicity,

I have formed generally in the shape of a U with the inherent tension ofthe U tending to force the arms outwardly against the walls of the unitthrough which the fingers extend and the following is a detaileddescription of the present embodiment of this invention showing thepreferred means by which these advantageous results may be accomplished.

With reference to the drawings,-1O designates the link unit of thebracelet chain which is formed with a top wall 11 and side walls 12,each of which latter walls has ears 13 and 14 projecting from theirends. The ears 14 are ofiset inwardly so that the ears 13 will overlapthe ears 14 and will lie flush with the side walls 12, and the piercings15 and 16 of these overlapping side wall portions will register or alignto receive the fingers 17 and 18 on the arms 19 and 20 which areconnected together by a bridge portion 21 forming a U-shaped connector22, the inherent resiliency of which tends to force the arms 19 and 20outwardly to keep the fingers 17 and 18 in the registering openings ofthe ears above mentioned to hingedly or pivotally connect adjacent unitstogether.

In detaching one unit from another,'it is merely necessary to insertsome sharp instrument such as a common pin in the space 23 between thearm 19 or 20 and the adjacent side wall 12 to withdraw its finger fromthe registering openings separating one link from another. Thewithdrawing of the arm 19 is shown in Figure 3.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.

I claim:

1. A chain comprising a series of units connected together, each unithaving spaced substantially parallel side Walls, the side Walls of oneunit having laterally displaced portions at one end thereof, thelaterally displaced portions of one unit and the side walls of theadjacent unit being in contacting parallel relation and havingregistering openings therethrough, and resilient elements having foldedends forming fingers projecting into said registering openings anddetachably connecting the units together.

2. A chain comprising af series of units connected together, each unithaving spaced substantially parallel side Walls, the side walls of oneunit having laterally displaced portions at one end thereof, thelaterally displaced portions of one unit and the side Walls of theadjacent unit being in contacting parallel relation and havingregistering openings therethrough, and resilient U-shaped elementshaving folded ends forming fingers projecting into said registeringopenings and detachably connecting the units together.

3. A chain comprising a series of units connected together, each unithaving spaced substantially parallel side Walls the side Walls of oneunit having laterally displaced portions at one end thereof, thelaterally displaced portions of one unit and the side Walls of theadjacent unit being on contacting parallel relation and havingregistering openings therethrough, and elements having resilient armswith folded ends forming fingers projecting into said registeringopenings and detachahly connecting the units together.
